This paper considers the problem of predicting a supply chain cost for prefabricated building construction under an uncertain situation. Based on the Activity-Based Costing (ABC) method, we establish a computational model to estimate the total cost of the prefabricated supply chain. The model can assist in not only finding the critical areas for cost reduction of the whole supply chain but also analyzing other costs of prefabricated construction projects. Furthermore, we provide a numerical example of prefabricated building construction to validate the results.

Scope management is a key issue in construction projects. This paper studies scope reductions. Potential reductions of project scope as well as budget contingencies have been a tool for cost control of governmental investments in Norway since 2001. This paper studies implementation of such reduction in major construction projects in different governmental sectors. Project representatives were contacted to obtain information about actual use of pre-defined potential scope reductions. Eight of the 14 studied projects did not implement any of the predefined reductions. Six projects implemented some of the reductions. These reductions were mainly general reductions of the quality of the facilities. The Norwegian reduction lists are based on an unusually high degree of specification of potential actions for cost control. International best practice is more concerned with general approaches. To function as intended, possible reductions should be possible to implement late in a project. General contingencies appear to be more effective for cost control than predefined scope reductions.

Un nuevo sistema de gestión de costes de proyectos de construcción para aumentar la competitividad y la trazabilidad para entornos de proyectos. El objetivo principal de la investigación es utilizar nuevos métodos de cálculo de costes en los proyectos de construcción para reducir y controlar las desviaciones de costes y algunas limitaciones que presentan los modelos tradicionales. La hipótesis de la investigación se basa en la capacidad sinérgica del cálculo de costes basado en actividades centradas en el rendimiento, en combinación con el método de cálculo de costes objetivo para fomentar la competitividad del sistema de control de costes para entornos de proyectos. El método se elaboró para controlar los gastos directos y generales del proyecto durante su ejecución. Se realizó una entrevista con 26 directores financieros en dos o cuatro ocasiones entre junio de 2016 y mayo de 2017 con el fin de validar y modificar el método. Siguiendo una entrevista semiestructurada, el método propuesto contribuyó a aumentar la precisión, la certidumbre y la rastreabilidad de los costes y proporcionó la integridad del sistema contable, técnico y operacional. Además, se analizan las desviaciones y se reducen los costes al considerar las condiciones competitivas y estratégicas. También se limita el coste objetivo de los paquetes de trabajo y se genera una alerta al finalizar cada uno de ellos. Además, de acuerdo con el test de Friedman, existe una capacidad competitiva significativa en comparación con el método convencional de control de costes en los proyectos y también se aplica en un estudio de caso. This research proposed a new method for project cost management based on Competitiveness and traceability in a case study and operational situation. The research hypothesis is based on the synergistic ability of performance focused activity-based costing in combination of the target costing method for encouraging competitiveness cost control system for project environments. The method was developed to control, direct and overhead costs of the project during its progress. Also, it uses the feature of activity-driven and different resource drivers to determine the types of costs with the effect of time driver for each activity. An interview was conducted with financial managers during two to four times with the aim of validating and modifying the method. According to a semi-structured interview, the proposed method contributed to increase the precision, certainty, traceability of costs and provided the integrity of the accounting, technical and operational system. It also analyzes deviations and reduces costs by considering competitive and strategic conditions. It's also limiting the target cost of work packages and causing an alarm on the completion of each. According to Friedman test, there is a meaningful competitive ability compared to the conventional cost control method in the projects and it is also implemented in a case study.

Cost reduction is the goal of building engineering cost control and the main way to effectively increase corporate profit gains. In this paper, a brief discussion on the contents of engineering cost control in the building structure design is presented. It aims to make enterprises truly recognize the important role of engineering cost control through preliminary analysis and discussion and improve overall strength by a series of improvement measures.
